Hi All ,
Help again appreciated ,
The car is running dog rough after years of pleasure , 134k on the clock .
On the ECS fault code reader i have - 16586 - PO20L - cyl 2 injector circuit - N31 open .
I have taken the spark plugs out and defo 2 cyl is not right .
1/ Do I need to change the injector (crap job I think )
2/ I have also been told it could be the wiring loom to the injector .

Any thoughts advice appreciated .
Chase.

No thoughts then ?
Yesterday I cleared the faults , drove 12 miles and no faults and the car ran fine !
Any ideas ?
